| Abstract [eng] |
This article contains research material about the efficiency of external walls of the living houses currently being widely renovated. Provided there are calculations of thermal resistances and changes of thermal losses for different thermo-insulation materials at various thicknesses of layers. The comparison was made between the thermal losses of walls of a renovated house and a non-renovated house. This study has analyzed five thermo-insulation materials having different values of thermal conductivity factor. It is concluded what influence thermal resistance value (R) has to direct linear change by changing insulation material thickness being used and has opposite proportion to thermal conductivity factor. The costs were calculated for the multi-storey house masonry wall of by using various thermo-insulation materials and their various thicknesses. This way it is determined that insulation of external walls of multi-storey house by using 0,1m neopor EPS100N. In experimental part research results are compared with each other and are presented graphically. The work consists of 6 parts: introduction, the methodical part, experimental part, conclusion, references, appendices. |
